Application August 7,

2 Claims.

The present invention relating as indicated to liquid containers has more particular reference to a container or barrel which is to be subjected to unusually severe usage during transportation and which must possess insulating properties for the protection of its contents.

One of the objects of our invention is to provide a liquid container having a metallic shell which will withstand the severest usage and being so constructed whereby dents and depressions incurred in the wall of the container incident to the reception of blows and impact may be readily removed in order that the container will main tain a constant volume.

Another object of the invention is to provide a combined wood and metal wall container in which the interior metallic shell or container is permitted to move slightly with respect to the outer wooden wall when the latter receives an unusual impact. In other words, the interior metallic shell is to be made, in a sense floating with respect to the outer supporting wooden structure.

Another object of the invention is to provide 25 simplified means of construction in such an above-noted liquid container in which damaged staves of the outer wooden wall may be quickly and individually removed and new staves inserted therefor, without aiiecting the assembly of the container.

Still anonther object is to provide a novel form of construction in the joints of the metal lining to eliminate crevices in which small particles of sediment or bacteria might accumulate. 35 To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain structure embodying the invention, such disclosed means constituting, however, but one of various structural forms in which the principle of the invention may be used.

In said annexed drawing:

Fig. l is a half section elevational view taken through the container; Fig. 2 is a bottom plan view of the container; Fig. 3 is an enlarged section of the upper right hand corner of Fig. 1; Fig. 4 is an enlarged view of the outer side of the bung; Fig. 5 is a perspective View of one of the metallic lining retaining segments.

Now referring more particularly to the draw ing, the container consists essentially of an outer wooden wall which is made up of a plurality of 1933, Serial No. 683,920

relatively thick staves l and an inner relatively thin metal lining or shell 2. The top and bottom walls of the metal shell 2 consist of the double wall members 3 and 4 and between which is positioned a layer 5 of insulating material. The top wall also includes an aperture and cover member 6, the more precise construction of which is set forth in our co-pending applications filed April 28, 1933, Serial Nos. 668,319 and 668,320

A series of hoops I are driven over the outside of the staves l in order to secure the latter in position. A plurality of small segmental lugs 8 which have a length equal to the width of the individual stave I are secured to the inside of such staves by means of suitable spiral nails or screws 9 and serve as a means for maintaining the inner metallic shell against longitudinal movement. The lugs 8 also have projecting flanges Ill which are adapted to seat into the staves in order to give'a more secure attachment. Since the retaining lugs B are made in segmental form and only extend for an arcuate distance equivalent to the width of each stave, it will be seen that whenever a stave becomes damaged that it is merely necessary to remove the fasten- 5 ers 9 and lugs 8, and then slide out the individual stave without disturbing the remainder of the container.

It is also contemplated that a very slight clearance be permitted between the edges of the 30 double seam joints 20 which join the side walls 2 and end walls 3 of the metal container, and the recesses 2| in the insides of the staves I. This clearance has been denoted by the reference letter a. In this manner, when the outer wooden 35 wall is subjected to severe impacts against its ends, the end walls of the inner metal container will be allowed to move slightly inwardly transferring such movement to the flexible metal sidewall 2 and thereby to absorb partially the effect of the impact. Thus the inner metallic container is in a sense made floating with respect to the outer Wooden wall.

Since there are certain shocks and impacts which are bound to be, transmitted to the inner metallic lining 2 and to cause dents or depressions in the latter, it is contemplated that such inner metal shell 2 be made relatively thin and flexible, and with such a flexibility that it is possible to submit the interior of the container to hydraulic or pneumatic pressure and thereby quickly conform the metal lining 2 to the interior of the outer wooden wall and in such a manner to remove any sustained dents or depressions. The net result of such a last-described structure is that the volume of the container may be very easily maintained at a constant during its entire life and regardless of the severity of usage.

A bung hole II is positioned in the side of the container. Such bung hole II consists of a metal ring I2 which is welded to the metal lining 2. The outer ends of the sleeve I2 are threaded as at I3 to receive a lock nut I4. The lock nut I4 in turn bears against a flanged ring. I5 which is forced tightly and securely to the wooden stave I. A wooden bung I6 may then be driven into the interior of the metal sleeve I2. A plurality of indentations I! are provided in the periphery of the lock nut I4 for the reception of a. suitable manipulating tool. In this manner, it will be seen that the stave in which the bung hole II is positioned may also be individually removed without disturbing any of the other staves. Thus by unloosening the hoop I, and removing the lock nut I4 and flanged ring I 5, the stave may then be lifted outof position.

Now directing attention to Fig. 3, it will be seenthatthe side wall 2 and top wall 3 of the metal lining are joined together in a double crimped or flanged joint 20. Ordinarily such a joint would result in leaving a small wedge shaped crevice in the area where the two walls come together. In order to eliminate such a joint, an inwardlydirected groove or channel I8 having a relatively sharp shoulder I9 is rolled into the side Wal 2 whereby such a crevice is eliminated and the meeting portions of the two side walls 2 and 3 contact each other at an angle of 90 or greater. The effect of the inwardly directed channel I8 is to make the side wall 2 conform to the rounded edge of the top wall 3 to a point where a substantially abrupt or rectangular meeting line may be obtained, thus eliminating the acute angular contact which would otherwise result if the channel I8 were not present.

Other modes of applying the principle of our invention may be employed instead of the one explained, change being made as regards the structure herein disclosed, provided the means stated by any of V the following claims or the equivalent of such stated means be employed.

We therefore particularly point out and distinctly claim as our invention:

1. In a liquid container, the combination of an outer wall composed of a plurality of staves, a metallic container positioned interiorly of said outer wall, and a plurality of abutment members secured to the inner faces of said staves at points adjacent and contacting with the ends of said metalliccontainer.

2. In a liquid container, the combination of an outer wall composed of a plurality of staves, a

metallic container positioned interiorly of said outer Wall, a plurality of abutment members having a length equal to the width of individual staves and secured to the inner faces of said staves at points adjacent and contacting with therendsof said metallic container.
